flit 1Z2 "Iv/m it may concern Be it known that 1, Josarrr A. RoNoI-IE'MI, a subject of the King of Italy, residing at ll'oonsocket, in the count-of Providence and State of R'h'ode island,- have invented certain new and useful Improvements in T pedd riting Machines, of which the follo vine; isa :t'ull clear, and exact description, such .will enable others skilled in the art to which it app'ertains to make and use the This invention rel: tes to typewriting machines, and one of the objects thereof is to I thereof; Fi

, necting may be actuated at proy ide newand improved means for conanism.

An'athcr object of the invention is to provide means whereby the spacing mechanism the instant of the com: mencement of the downward or upward strokes of the key-levers or space bar.

Another object is to provide new and improved means for arresting the movements of various operative parts of a typewriting machine in a silent manner.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists-in the features of construction, combinations of elemer cs and'arrangement of parts which Will be exemplified in the construction hereinafter set forth, and the scope of the application 01' which will be indicated in the 01 lowing claims.

In the accompanying drawings, wherein is illustrated one of the various possible embodiments of my invention,.Figure-1 is a plan view illustrating the various features 2 is a side elevation t ereof,

partly in schfiion, 2 -2, Fig. 1; Fig. 3 is a view similar to Fig. 2, the parts-being shown in a different position'; Fig. 4 means for arresting the universal bar, the view being taken substantially on line 4-4, Fig. 2, and the parts being shown mal position; Fig-5 is a view similar to Fig. 4, but taken on the line 5-5, Fi 2, showing the position of the parts when-the universal bar is depressed by one of the, key levers; Fig. 6 is a sectional view, on an enlarged scale, taken on line 6-6, Fig. 5.

Similar reference characters refer to simithe space bar with the spacing mech taken substantially on line is a rear view, showing the in norlar parts throughout the drawings. 4 I

Referring now to the drawings, 1 denotesa portion of the framing of the machine and 2 the escapement shaft carrying the escapementwheel 3 and the feed-pinion 41 which meshes with the, carriage rack, a portion of which is shown at 5; 6. represents a rocker .member upon which is mounteda fixed dog 7 and a movable dog 8 which cooperate with the-escapement wheel 3 to aii'ord feed of the carriage. This rocker member is mounted upon pivot screws 10 carried by brackets. 11' erected upon the frame of the machine and is provided with a forwardly extending the several figures of i arm 12 to which it is'attached as by means of a pivot-screw l3 and an actuating linl; 14, said link being in turn connected, as by means of a pivot-pin 15, to an arm 16 mounted loosely upon the universal rock shaft 17. Rock shaft 17 extends transversely of the machine and is supported at its ends by trunnion screws 18extending through the side walls of the framing of the machine. Stops for limiting the oscillatory movemznts of rocker member 6 are provided at 20 and 21, respectively, said stops beingvconstituted by pointed screws adjustably mounted in an extensionv 22 of one of brackets 11. Arm 12-of rocker member 6 engages these screws when oscillated, and the extent of oscillation thereof is determined by such engagement; Arm 16, which is mounted upon the universal rock shaft, is provided with a .cone-. shaped port-ion 23'w'hich is received in a conical-shaped recess 2e formed in a collar 25 fixed upon said rock shaft, as by means of a pin 26. The cone shaped portion 28 is maintained in engagement with the walls of recess 24 by means of an extensile spring 27 positioned upon shaft-17 and interposed betweensaid arm and acollar28 fixed upon the rock shaft and held in any desired adjusted position" thereon, as by means of aset-screw 30. The construction just described estab: lishes a frictional connection between the universal rock shaft and the rocker member with either of stops 20 or during a furtlier rocking movement of said 7" 21', whereupon rock shaft the frictional engaging surfaces of the collar 25and arm 16 will slip on each other until the universal shaft completes its full stroke. It will accordingly be seen that the rocker member which carries the feed dogs will be oscillated at the instant of commencement of rotation of the universal rock shaft in either direction.

The key levers, one of which is shown at 31, rest upon the universal bar 32 which, as shown, is suspended upon links 33 carried by arms 34 mounted upon the universal rock shaft 17, cushioning means, as at 85, being interposed between the universal bar and the key levers.

Mounted upon a stud-screw 36 threaded into a bracket 37 suitably attached to the framing of the machine is an oscillatory cam member l0. This cam member, which is shown in normal position in Fig. 4, has a cam path -11, the upper end of which is disposed substantially vertical, said vertical portion merging into a concave portion 42, the surface of which is formed upon an arc of decreasing radius and ending in a portion 43 which is disposed substantially concentric to the axis of oscillation of the cam? member. 44 indicatesa roller which is journaled upon a pivot pin 45 supported in ears 4:6 depending from the side port-ions 17 and l8 of the universal bar. This roller, in the present instance, is located centrally of the universal bar directly above the central axis of the stud-screw 36 upon which the cam 40 is mounted, the cam path 41 of said cam member being held in engagement with said roller by means of a retractile spring attached to a rearward extension 51 of the cam member and interposed between said extension and a bracket 52 fixed in the framing of the machine. It will beseen that during the downward movement of the universal bar, as when a key lever is depressed,

; roller 44 will cause an oscillation of the cam member 40 from the position shown in Fig. l of the drawings to that shown in Fig. 5, the roller meanwhile traversing the curved portion 42 of the cam path until it reaches the portion 43 thereof which is disposed concentrically with the axis of oscillation of the cam member, whereupon the movement of the universal bar will be arrested. It will also be seen that a constantly increasing resistance is interposed to" the downward movement of the universal bar and that the same will be arrested without any impact or concussion whatever. I In order to eliminate any tenderoyof the universal bar to movement in an endwise direction duri 'ig' depresslon caused by the engagement of roller ist with the oscillatory cam member, a tiled bracket 53 is provided said bracket having; avertically disposed upon pivot pin 4:5. Theengagement of these rollers with this bracket causes the universal bar to travel downwardly in a vertical line. The universal bar is restored to normal position after depression by means of a spring 57 which is extended between a pin 58 fixed to the side wall of the machine and a rearwardly ex tending portion 60 of one of the arms 3% from which theuniversal bar is suspended.

(31 denotes the space bar which is sup levers 62 and 63 which are mounted upon a rock shaft 64 journaled upon trunnionscrews 65 threaded through brackets 66 formed upon the framework of the machine, and extended between space levers 62 and 63 is a rod 67. Upon this red is mounted a link 68, said link being pivotally attached, as at 70, with a link 71, the upper end of the latter link being pivotally attached, as at 72, to an arm 73 fixed upon the universal rock shaft. Links 68 and 71 furnish an actuating connection between the space levers'and the universal rock shaft, so that, when the space bar is depressed, the universal rock shaft will be oscillated to ,actuate the spacing mechanism; and it will be noted that, when the space bar is depressed, the universal bar, through its connection with the universal rock shaft, will also be depressed, whereupon the oscillatory cam member 40, will, through the above described mechanism, operate to arrest the downward movement of the space bar without impact or concussion. The space bar is restored to its normal position after depres sion by means of spring members 74: and 75, fixed as at 76 to the framework of the machine, said springs engaging with collars 77 fixed upon rod 67,

against endwise movement upon said rod. Link 68 is provided with a projecting car 78 against which a fiat spring SO'engages said spring exerting a tension tending to swing link (38 in the direction indicated by the arrow, so that when the universal bar is depressed by a key lever, links 68 and 71 will be flexed at their points of pivotal connection, as shown in Fig. 3 of the drawings, thus allowing the space bar to remain stationary when the universal bar is depressed ,by the key levers.

the present embodiment of my invention, the operation thereof, which should be obvious, is substantially as follows: As has been explained above, when one of the key levers is depressed to effect printing, the universal bar 32 is correspondingly depressed, thereby, through its connection latter and actuating the space mechanism, said latter mechanism being frictionally connected to the universal bar so as to be ported upon the forward ends of spacesaid collars also operating to maintain link 68 Having thus described the construction ofwith the universal rock shaft, oseillati.ngthe' 16 similarly actuated through above construction and 1,094,816 p i a.

actuated at the instant of the commence 'nieutof the downward'stroke of a key lever. Duringthe downward 'motion of the universal bar, roller 44 travels along the cam path 41 of the oscillatory member 40 and downward motion, rollers and 56 traveling upon the vertical-face of bracket 53 cause the universal bar to travel downwardly in a vertical line. hen the space bar is depressed, the spacing mechanism is the connection of the universal rock shaft 17 with said space bar, and the universal bar is at the same time moved downward without, however, affecting any of the key levers. AS- 20 will be understood, the links 68 and 71 flex or bend at their point of pivotal connection whenever the universal bar is depressed by a key lever. 1

It will accordingly be seen that I have 2 5 provided mechanism well'adapted to attain,

among others, all the ends and objects above .pointed out, in a simple, yet efficient, manner. The frictionalconnection interposed between the universal rock shaft and spacing mechanism provides for an actuation of the spacing mechanism at the instant of the commencement of the movement of the universal rock shaft in either direction, and thus quickens the feed of the carriage with 5 out in any wise obstructinga full stroke of the universal bar or the key or. space levers.

Another advantage inherent in the'present construction is that the collapsible link connection interposed between the space 0 levers and the universal rock shaft permits either the space baror the key levers to be actuated without causing a corresponding movement of the other.

Still another advantage inherent herein is 5 that the movements of all the operative parts are noiselesslynirrested by means of the cam member interposed beneath the universal bar.

As many, changes could be made in the widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that allmatter contained in the above description or- I 5 shown in the accompanying drawingsishall be interpreted as illustrative and not. in a limiting sense. p c Having described my invention, what I claim as new and desire to secure by Letters 3 Patent 1st.
